Soft Threshold Estimation for Varying-coefficient Models (2007)
An alternative penalized likelihood estimator for varying--coefficient regression in generalized linear models is proposed. The estimator leads to a sparse representation of the results as sums of a...
Generalized Soft-Thresholding and Varying-coefficient Models (2007)
this paper, we propose a general method for estimating functions within the generalized linear model setup. The proposed estimator yields an adaptive economical description of the estimates in terms...
Inference in High Dimensional Generalized Linear Models based on Soft-Thresholding (2001)
This paper focuses on GLM, having many terms in the linear predictor,
Inference in High Dimensional Generalized Linear Models based on Soft-Thresholding (1999)
We propose a new method for estimation of a high number of coefficients within the generalized linear model framework. The estimator leads to an adaptive selection of model terms without substantial...

A nonparametric multiplicative hazard model for event history analysis (1998)
FAHRMEIR, LUDWIG, KLINGER, ARTUR
A major issue in exploring and analysing complex life history data with multiple states and recurrent events is the development and availability of flexible models and methods that allow the...
Generalized Soft-Thresholding and Varying-coefficient Models (1997)
We propose a new method for estimation of unknown functions within the generalized linear model framework. The estimator leads to an adaptive economical description of the results in terms of basis...

Additive, Dynamic and Multiplicative Regression (1995)
Fahrmeir, Ludwig, Gieger, Christian, Klinger, Artur
We survey and compare model-based approaches to regression for cross-sectional and longitudinal data which extend the classical parametric linear model for Gaussian responses in several aspects and...
Identification of Prognostic Factors with Censored Data (1995)
Dannegger, Felix, Klinger, Artur, Ulm, Kurt
A major issue in the analysis of diseases is the identification and assessment of prognostic factors relevant to the development of the illness. Statistical analyses within the proportional hazards...
A nonparametric multiplicative hazard model for event history analysis (1995)
Fahrmeir, Ludwig, Klinger, Artur
A major issue in exploring and analyzing life history data with multiple states and events is the development and availability of flexible methods that allow simultaneous incorporation and estimation...
Identification of Prognostic Factors with Censored Data (1995)
Felix Dannegger, Artur Klinger, Kurt Ulm
this paper we use tree based models and varying coefficient models to allow for detectability of prognostic factors with possibly nonadditive, nonlinear and time--varying impact on disease...
Additive, Dynamic and Multiplicative Regression (1995)
Ludwig Fahrmeir, Christian Gieger, Artur Klinger
this paper we will focus on penalized least squares and likelihood methods as a unifying modelling and estimation approach. From this point of view, the smooth functions f j () are unknown, but...
A Nonparametric Multiplicative Hazard Model for Event History Analysis (1995)
Ludwig Fahrmeir, Artur Klinger
this paper we consider a nonparametric multiplicative hazard model that takes into account these aspects. Embedded in the counting process approach, estimation is based on penalized likelihoods and...
